HAZOP方法在对羟基苯甲醛车间火灾事故分析中的应用

Application of HAZOP approach in the fire accident analysis of p-hydroxybenzaldehyde workshop

对羟基苯甲醛是一种十分重要的精细化工产品,主要采用对甲苯酚催化氧化法合成。为了提高PHBA合成工艺和装置的安全性,首次采用了危险与可操作性分析法对对甲苯酚催化氧化法合成PHBA的事故案例进行分析,分析了火灾事故发生的原因,提出了相应的安全对策措施及建议。与传统的事故分析方法相比,HAZOP分析更深入、更全面,对工艺设计的改进和设备的选型具有重要指导意义。

p-Hydroxybenzaldehyde （ PHBA） is a very important fine chemical products,which is mainly synthesized by catalyzed oxidation of p-cresol. In order to improve the safety of production process and production unit in the synthesis of PHBA by catalyzed oxidation method,Hazard and Operability Analysis （ HAZOP） is adopted for the first time in order to analyzing the cause of the fire accident in p-hydroxybenzaldehyde workshop and putting forward the corresponding security countermeasures and suggestions. Compared with the traditional methods of accident analy-sis,HAZOP analysis is more deeper and more comprehensive,which is important for the improvement of production process design and equipment selection.
